Bitcoin is now trading above $7200 and continue to rise from the last two months. Bitcoin is now trading above 50 and 100 weekly MA which is known as a bullish sign. The golden cross has already happened (daily 50 MA crosses 200 MA).
Bitcoin has 14 green weekly candles in the last 17 weeks.
Even after the Tether, Bitfinex fud and Binance hack the price continue to rise.
Is the Bitcoin bull run started?
What are the main leading factors of this bull run?
We cannot really tell, this can just be a price correction. There are plenty of happenings in the crypto market lately, mostly negative news like the Binance security breach. The price pumped high and also dumped fast in the last 24 hours. I cannot find any reason to tell exactly that this is a bull run, and it is very far from half of its peak price in 2017, there is a very long way to go.
